NEW YORK (AP) — Red isn't just a trend at The Heart Truth runway show, it's a tradition: The Red Dress Collection, modeled by celebrities to draw awareness, has become the kick off to New York Fashion Week.

Minka Kelly, Toni Braxton, gymnast Gabrielle Douglas, Kelly Osbourne and Kris Jenner, with daughters Kendall and Kylie, were among those donning designer dresses and towering heels Wednesday.

It's the shoes that have many stars fearing they'll trip up. Actress Brenda Strong says her red spiky stilettos were the most intimidating part of the catwalk experience.

She had a little experience modeling, though. She was a former Miss America contestant.

Kelly, wearing Oscar de la Renta, previously walked in last year's show. Her best tip as a runway veteran runway was to wear shoes with straps.
